Re: [RFC PATCH] nfs: Support posix_fadvise(POSIX_FADV_RANDOM) on nfs server.

Hi Namjae,

I'm glad you also see the usefulness of sending such hints to the NFS 
server.

Beyond reviewing the  NFSv4.2 spec, it would also be very useful to 
implement a version of IO_ADVISE and show performance results with your 
traverse test (among others).  If you have time for this, that would 
really be helpful in ensuring the usefulness of IO_ADVISE.
